Slightly off-topic,- I am quite astounded by the apparent disparity between assigned and reported altitudes, V those purported to be returned by radar.
It is a well-documented fact that radar speed-traps return a wildly inaccurate return from fibreglass and Composite motor-bodies...I think Alloy also reflects differently......many motorists have successfully defended themselves from speeding-charges due to this.
So, (I know, apples and oranges) Do Composite aircraft show an erroneous height return?
As the pilot apparently confirmed his pressure-setting and would seem to have , at some points, have flown the assigned alt. this begs the question,- did the pilot deliberately lie to ATC, in the erroneous belief they "couldn't see" him, or did he have "selective" instrument -failure ( Thales Pitot iced?
)
under the circumstances, sounds like PPP due to lack of PP P
(for other non-pilots (and Journo's)...the acronym = Prior Planning Precludes..Piss-Poor Performance.)
Edit....OK, The Altimeter relies on Static...back yo the Trevor Thom's.
